Intermediate Oman
Oman
Two seas, monsoon upwelling, and Arabian diving almost nobody has on their list
A country with coastline on two distinct seas and a phenomenon almost no tropical destination has: every summer, the monsoon pushes cold, nutrient-rich water from the depths to the surface, and the sea changes color and inhabitants for months.
In this profile you'll find how the country's three diving zones differ, how the monsoon upwelling splits the year into two opposite regimes, when whale sharks show up, what the currents in the northern fjords are like, and what level each zone requires.
This is the destination that proves the Arabian Peninsula has much more than the Red Sea, and one of the few places where a diver can see firsthand what a seasonal upwelling does to an entire ecosystem.
Geography and access
Oman occupies the southeastern corner of the Arabian Peninsula and has coastline on two distinct bodies of water: the Gulf of Oman to the north and northeast, and the Arabian Sea to the south.
The far north, a mountainous peninsula separated from the rest of the country, is full of fjords: narrow sea inlets between bare rock walls that drop into the water. Diving there is wall diving, with current at the mouths and a very distinctive look, closer to a Nordic fjord with warm water than to a tropical reef.
The central zone, off the capital, has a group of islands declared a nature reserve, with well-preserved hard coral reefs, and is the country's most accessible and most-dived area.
The south, facing the Arabian Sea, is where the upwelling hits hardest. During the summer monsoon the water cools drastically, fills with nutrients, and the ecosystem transforms; outside that window, it offers reefs and wrecks under very different conditions.
International access is through the capital's airport, with domestic flights or long road transfers to the north and south. The country's distances are considerable.
